I'm surprised that nobody has posted on here on this topic, but as you probably all know, it is the intention to end HST workings before the beginning of the new timetable on May 19th.

Plans are apparently afoot to have a grand finale at Paddington on Saturday 18th May when the last four will depart within half an hour of each other. The diagrams for the day (that have been copied and pasted from another forum so no guarantee as to accuracy) are as follows:

0657 PLY PAD
1045 PAD SWA
1429 SWA PAD
1830 PAD TAU
2132 TAU EXD

0729 EXD PAD
1121 PAD GMV
1435 GMV PAD
1815 PAD CNM

0645 BRI SWA
0929 SWA PAD
1330 PAD BRI
1600 BRI PAD
1822 PAD HFD

0650 PNZ PAD
1300 PAD BRI
1530 BRI PAD
1803 PAD PLY

Plan is for 1803/1815/1822/1830 departures to be side by side in Paddington Plats1-4.

There is also a "Farewell special" on 1st June, with profits to be donated to Action For Children:

GWR have now announced that the final normal HST departure from Paddington, the 1830 to Taunton via Bristol, will have compulsory seat reservations.

So if you want to ride on it, get your tickets ASAP if not before :)

Well, it's not the "end of HST operations" quite Robin- just here as you probably know some have gone to Scotland.

'Tis a sad day though. Who'd have thought when these icons first arrived in 1977 that we'd still be riding round on them to this very day - 42 years later. A brilliant design and success - probably one of the best ever and what workhorses they've been. And that's coming from a hydraulic man, whose beloved Westerns and they finally replaced.

My four particular memories from the distant days of their first introduction:

1. Coolant loss during the hot summer, when every platform had an opo stood at each end with a 45 gallon drum of coolant in tow on a platform pull about truck, to see how much could be pumped in at each stop to get those early Valenta engines and their initially slightly under-rated and venting cooler groups to the next station, and:

2. The Star Trek style swishing doors - who'd not have been sold on Star Trek in real life in the 1970s? Perfectly fine until some prat came along and stood their poorly balanced suitcase on the sensor mat!

3. Of course, that Valenta roar and how children would cover their ears and run away from the power cars as hey ran up ... Awesome, if rather dated engines now and they eventually did so well for so many years.

4. The original guards / parcels compartments at the end of each power car. How their use (and life in general) changed over the years.

Interesting memories Jules.

There was a time in the 80's when a particularly pedantic CM&EE (then RM&EE) forbade us from topping the cooling system in service due to the potential damage to engines by filling with cold coolant. You can understand his sentiment that we were treating the symptom of the problem not its cause. It was a policy which was gradually eased but it did focus the mind on sorting out the leaks.

If you have read the book on how Star Trek was produced the 'automatic' sliding doors were actually operated by a stage hand standing behind the scenery. The swishing noise was superimposed. HST sliding doors were obviously automatic as we couldn't afford to employ lots of doormen! (or women).

There was a time when dispatch staff at certain stations including Swindon were issued with ear defenders due to the excessive noise levels from the Valenta engine in the higher notches when accelerating. It was not such a serious problem when the Valentas were replaced with the much quieter MTU engines.

The original guard's van area in the power car caused a lot of complaints about rough riding partly due to the lack of air suspension. It led to the introduction of the TGS 44xxx series of trailer cars. The vacated area in the power car eventually housed the cupboard containing the Automatic Train Protection (ATP) equipment.

An experimental vehicle was trialled years later designated TSCD (Trailer Standard Conductor Disabled). It was designed to be formed in the centre of the rake making the Senior Conductor more accessible to the customer and with a disabled toilet years before they became compulsory. I think it was numbered 45084. No idea what eventually happened to it but it was a one off.

I don't have any practical experience on the MTU engined power cars as I was transitioning from the engineering department to operations when they were introduced. With the old Valenta engines there were frequent problems starting from hot on short turnrounds e.g. at Penzance where it was mandatory to shut down the west end power car under the overall roof. We did have a technique of 'trick starting' by manually closing relays and contactors but when the control cubicles were re-engineered the operating arms became less accessible. There was also the issue of safety when playing around inside a live cubicle so you had to know where not to put your fingers. Even a dead power car had a potentially live 415 volt supply close by fed from the other power car. When we encountered the 'Electricity at Work Regulations' for the first time it focused the mind a little on some of our 'get out of jail free' practices. Didn't stop us doing it though!

I once talked a non-technical member of staff through the trick start procedure over the phone when an up service failed on one engine being unable to climb into Liskeard. I was given a right royal rollocking the following Monday for putting him at risk. Managed to get 400 passengers on the move though avoiding a considerable delay waiting for maintenance staff to travel by road from Laira on a Summer Saturday afternoon.

I like to think that experienced maintenance staff wouldn't have needed to be told what to do. Most likely they would have had a few more dodgy tools in their box than me.

We never had a definitive answer to to failure of hot engines to start but the theory was 'heat soak' whereby the engine governor oil became too thin due to residual heat rising once coolant circulation ceased.

Well, there's certainly a case for running a hard worked engine at idle for several minutes before shut down, just to keep the coolant circulating and prevent any hot spots developing.

Likewise, particularly with the older Maybachs, engines that have been idling for an extended period or are started on a "hot start and away" should not be asked to deliver full output for several minutes afterwards, to allow the coolant to fully circulate at a proper rate and even out any temperature gradients.

Having run these ancient Maybachs for 40+ years now, I often think we've probably discovered more of their foibles than BR might have, despite the fact they were dealing with a lot more of them than we've ever had to.

I've heard numerous stories of the looks of sheer horror on the faces of German Maybach engineers who came to "observe" their beloved engines whilst they were still in BR service!
